NVIDIA GeForce RTX 3070 Ti vs NVIDIA GeForce RTX 5070 Ti Mobile Comparison

The NVIDIA GeForce RTX 5070 Ti Mobile and the NVIDIA GeForce RTX 3070 Ti represent two different generations of laptop and desktop graphics, separated by process technology, architecture, and intended power envelope. The database shows the RTX 5070 Ti Mobile edges out the older RTX 3070 Ti in average benchmark score (35435 vs 29945, an 18.3% gap), but the head-to-head results are far closer than that average suggests, with the RTX 3070 Ti actually winning more individual tests (5 vs 4). This comparison is not a simple generational stomp; it is a trade-off between modern efficiency and raw legacy compute throughput.

The Verdict

The data points to a clear split: pick the RTX 5070 Ti Mobile if you prioritize newer API performance, higher memory bandwidth per watt, and a platform that fits into a compact IGP form factor with a 60 W TDP. Its wins in DirectX 11 (23.4% ahead), DirectX 12 (12.1% ahead), and OpenCL (20.2% ahead) show it handles modern workloads better. Pick the RTX 3070 Ti if you need raw compute throughput and legacy rasterization strength; it wins in DirectX 10 (2.6% ahead), DirectX 9 (0.8% ahead), 2D graphics (7% ahead), and GPU compute (12.9% ahead). The RTX 3070 Ti also holds a narrow Vulkan edge (0.2% ahead), making it the more balanced choice for older titles and compute tasks. The RTX 5070 Ti Mobile sits in the 80th percentile of all GPUs, while the RTX 3070 Ti sits in the 75th, so neither is a top-tier outlier; both are solid mid-to-high performers with distinct strengths.

For users building a thin-and-light system, the RTX 5070 Ti Mobile is the only realistic option, as it is an IGP-class part with no power connectors and a 60 W TDP. For desktop users with a 600 W PSU recommendation and a dual-slot chassis, the RTX 3070 Ti offers higher raw FP32 and texture rates, making it a better fit for compute-heavy workflows. Do not buy the RTX 5070 Ti Mobile expecting it to beat the RTX 3070 Ti in every test; the data shows it loses in compute and legacy APIs, so choose based on your actual workload mix.

Architecture Differences

The RTX 5070 Ti Mobile uses the GB205 chip on TSMC's 5 nm process, packing 31,100 million transistors into a 263 mm² die. The RTX 3070 Ti uses the GA104 chip on Samsung's 8 nm process, with 17,400 million transistors on a much larger 392 mm² die. This gives the newer chip a transistor density of 118.3M per mm² versus 44.4M per mm² for the older one, a massive efficiency advantage. The RTX 5070 Ti Mobile is built on Blackwell 2.0 architecture, while the RTX 3070 Ti uses Ampere. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical, but the underlying hardware differs significantly.

Memory is a major divergence. The RTX 5070 Ti Mobile has 12 GB of GDDR7 on a 192-bit bus, delivering 672.0 GB/s of bandwidth. The RTX 3070 Ti has 8 GB of GDDR6X on a 256-bit bus, delivering 608.3 GB/s. The newer card has more capacity but a narrower bus, yet still achieves higher bandwidth due to GDDR7's faster effective speed (28 Gbps vs 19 Gbps). The RTX 5070 Ti Mobile also uses PCIe 5.0 x16, while the RTX 3070 Ti uses PCIe 4.0 x16, and the mobile part has 46 ray tracing cores and 184 tensor cores, versus 48 RT cores and 192 tensor cores on the desktop card. The RTX 3070 Ti actually has more shading units (6144 vs 5888), more TMUs (192 vs 184), and more ROPs (96 vs 80), which explains its higher pixel and texture rates.

Where Each One Wins

The RTX 5070 Ti Mobile wins in modern API workloads. Its DirectX 11 score of 237 versus 192 (23.4% ahead) and DirectX 12 score of 102 versus 91 (12.1% ahead) show it handles current game engines and features better. Its OpenCL score of 143870 versus 119718 (20.2% ahead) indicates strong compute performance in applications that use OpenCL for acceleration. The 3DMark Steel Nomad DirectX 12 test is not available for the RTX 5070 Ti Mobile, but the RTX 3070 Ti scores 3478 there, which is not directly comparable due to missing data. For general 3D rendering, the PassMark G3D score favors the mobile card by 2.8% (24004 vs 23356), a narrow but consistent win.

The RTX 3070 Ti wins in legacy and compute-heavy tasks. Its GPU compute score of 11601 versus 10101 (12.9% ahead) is the largest margin in its favor, reflecting its higher FP32 throughput of 21.75 TFLOPS versus 17.04 TFLOPS. It also wins DirectX 10 (155 vs 151, 2.6% ahead), DirectX 9 (261 vs 259, 0.8% ahead), and 2D graphics (1055 vs 981, 7% ahead). The Vulkan score is nearly identical (139541 vs 139213, 0.2% ahead for the RTX 3070 Ti), so either card works for Vulkan titles. If you run older DirectX 9/10 games or use GPU compute for rendering or analysis, the RTX 3070 Ti is the better performer. If you play modern DirectX 11/12 games or use OpenCL-accelerated apps, the RTX 5070 Ti Mobile pulls ahead.

Head-to-Head Benchmarks

The biggest win for the RTX 5070 Ti Mobile is in OpenCL, where it scores 143870 versus 119718, a 20.2% advantage. This is followed by DirectX 11 (237 vs 192, 23.4% ahead) and DirectX 12 (102 vs 91, 12.1% ahead). The 3DMark G3D score is also in its favor, but only by 2.8% (24004 vs 23356), showing that overall gaming performance is close. These wins suggest the newer architecture is better optimized for modern APIs and compute standards.

The biggest win for the RTX 3070 Ti is in GPU compute, where it scores 11601 versus 10101, a 12.9% advantage. This is a substantial margin and reflects its higher raw compute throughput. The 2D graphics win is also notable at 7% (1055 vs 981), and the DirectX 10 (155 vs 151) and DirectX 9 (261 vs 259) wins are narrow but consistent. The Vulkan score is essentially a tie (139541 vs 139213, 0.2% ahead for the RTX 3070 Ti), so neither card has a meaningful edge in Vulkan titles.

Looking at the delta percentages, the RTX 5070 Ti Mobile's wins are larger in magnitude (20.2%, 23.4%, 12.1%) than the RTX 3070 Ti's wins (2.6%, 0.8%, 7%, 12.9%). This means the mobile card dominates in its favored workloads, while the desktop card wins more tests but by smaller margins, except for GPU compute. The RTX 5070 Ti Mobile also has a higher average benchmark score (35435 vs 29945), driven by its strong OpenCL and modern API results. For users who care about average performance, the mobile card is better; for users who care about consistency across a wide range of tests, the desktop card wins more often.
